NMR at Very Low Temperatures: Population Difference Thermometry

Low temperature physicists have employed magnetic resonance techniques to study the fundamental properties of materials at very low temperatures from the earliest days following the discovery of NMR. Many of the familiar degrees of freedom such as phonons and vacancy propagation are frozen out at temperatures below a few degrees Kelvin and magnetic resonance provides one of the most powerful me...

High magnetic field corrections to resistance thermometers at low temperatures

Life at high temperatures.

Water environments with temperatures up to and above boiling are commonly found in association with geothermal activity. At temperatures above 60 degrees C, only bacteria are found. Bacteria with temperature optima over the range 65 degrees to 105 degrees C have been obtained in pure culture and are the object of many research projects. The upper temperature limit for life in liquid water has n...

Nanotribology at high temperatures

Recent molecular dynamics simulation results have increased conceptual understanding of the grazing and the ploughing friction at elevated temperatures, particularly near the substrate's melting point. In this commentary we address a major constraint concerning its experimental verification.
